Hi, Dean --
Sounds like a pretty nice setup and will give you all-band capabilities.
Needless to say the TX455 (18 sq. ft. @ 50 MPH) will be overloaded at your
75 MPH county wind speed rating by a significant factor (estimated 166% of
rated capacity). Don't extend it all the way and you'll get some overhead
back again. Well, you asked.
My other question mark is the rotator. The G800 doesn't have as much
braking torque as the Ham IV; either of which IMO are marginal for you. The
Effective Moment/K-Factor of the TH11DX (weight times turning radius) is
1936; the G800 is rated at 1299 ft-lbs and the Ham IV is 2800 ft-lbs. I
still think you need more starting torque because of the weight of the TH11
and we haven't even factored in the 40M rotating dipole yet. The G1000 or
T2X TailTwister are better and the Create RC5A2 has even better specs for a
little bit more money. TOWER TECH handles the Create line because of its
worm gear (no brake required) drive, big transmission gears and reliability
per comments from TowerTalkians.
